C. Soumillon
Fair A/E compares wins with a margin-stripped market expectation. Favourite-heavy samples — top yards, leading riders — naturally read a few points warm, so 1.05 means "beat the margin-free market read", not "the market underrates this by 5%".
Rides around 520 times a season, almost all on the flat, winning on 16% of them — level with the margin-free market read across five seasons (Fair A/E 1.01). Riding last-time-out winners the record reads 21% (439 rides). The rider is quiet just now — 2 winners in the last fortnight, below their own baseline.
It is weakest at Ascot (8.9% over 45 rides) — the widest gap in the record. Rides on last-time-out winners have been a positive signal at 21% (n=439, Fair A/E 1.07), but rides in big fields of 14 or more have been a poor signal at 11.1% (n=867, Fair A/E 0.99). Right now the rider is in a quiet spell: 2 from 19 rides in the last 14 days (10.5%, 5.1pts below the 15.6% baseline). F-H Graffard supplies 10% of the rides and beats the rider's average (23.5% vs 15.6%, A/E 1.00) — the market has that partnership priced right. The record reads poorly on Good to Firm going — 8% over 50 rides, 7.6pts below the baseline. 595 Group and Graded wins sit in the archive record — the biggest prize the rider has landed: the Qatar Prix de l'Arc de Triomphe at Longchamp (FR) (Oct 2008, £1,680,588). The standout partner of the record: Vazirabad (FR) — 11 wins from 15 rides together. Seasonally, the rider fires Nov–Feb.
Riding patterns
the angles behind the record · vs 15.6% baselineEach tile is the record in that situation vs the 15.6% baseline — descriptive splits with the sample always shown, for you to weigh. Tiles under 30 runs render muted. First rides are the first captured pairing of horse and rider; last-time-out winners are horses whose previous captured run was a win; claiming rides are runs where the rider carried a weight claim. Group / Graded covers pattern and listed races.

Each pick was a KTB figure’s choice before the off — the published KTB Selection, the top-rated horse on KTB Rating, the fastest on KTB Speed — settled against the result the next morning and never worked out again; “did not run” is counted apart. GB and Irish races only. A record of weeks so far: read it as a count, not a verdict.

- What is C. Soumillon's Fair A/E?
- 1.01, from 2,606 rides with a computed fair probability since 2022. Fair A/E compares actual wins with a margin-stripped market expectation, so 1.00 is par: above it the wins came at bigger prices than the margin-free market implied, below it they did not.
